BEDSPRING REENFORCEMENT.

Application led January 1S, 1922. y Serial No. 530,203.

To all whom t may concern:

vented new and useful improvements in Bed` gring Reenforcementsp ofwhich the following is a specification.

rhis invention is designed to 11e-enforce bed springs, especially wovenwire springs to prevent the sagging which ordinarily' takes place insuch springs.

rlie invention is illustrated in the accompanying drawings as followsFig. 1 shows a plan View of the re-enforcement.

Fig. 2 a central sectio and a bed. i

1 marks the bed posts, 2 the rails vof the bed, 3 a woven wire springmounted on the bed, and e a mattress on the spring. These are ofordinary construction. j

The spring re-enforcement comprises a flexible platform 5. T his is madeup of peripheral flat bars 6 united at the corners by rivets 7. F latbars 8 extend diagonally from corner to corner7 being secured at thecorners by the rivets 7.

A spring 9 engages the platform at the point of crossing of the bars 8.lt is supported by a post '10 resting on a cross bar 11. The cross barhas the rail engaging members 12 with the hooks 13 resting on the rails2, rlie post 10 is .preferably made up of the screw-threaded member llon which the spring 9 rests and a screwthread ed member 15 extendingupwardly from the cross bar and the threads on the members 14 and 15being reversed and engaged by a turn buclrle 16 by which the post may beexpandedto adjust the spring 9.

ln order to adjust the rail engaging members to different widths of bedsthe cross bar 11 is provided with the screw-threaded nuts 17 and themembers 12 are screwethreaded at 18 so that they may be screwed into orout of the cross bar 11 to adjust them to dierent widths of bed.

through the device In order to yieldingly engage the pel ripheralportions of the platform l prefer to provide a flat metal spring 19,resting on the post 10 having the bends 20 at their outer edges andengaged to the peripheral bars 6 at 2l, the bends 2O permitting of theyielding extension of the spring as it is deflected. y i

With this device, therefore, there is a yielding support which preventsthe sagof the bed of the woven wire type and can loe readily applied tobeds in use.

That I claim as new is 1. ln a bed spring re-enforcement, thecombination of a supporting bar; a flexible platform above the bar; andan adjustable spring connection between the bar and plat` formcomprising a spring and an expanding post for adjusting the spring.

2. ln a bed spring re-enforcement, the combination of a supporting bar;a flexible platform above the bar; and a spring connection between thebar and platform comprising springs supported at a centrally lo- `-catedpoint on the bar and engaging the platform centrally and peripherally.

3. ln a bed spring re-enforcement, the combination of a supporting bar;a'fflexible platform above the bar; and a spring connection between thebar and platform comprising a coil spring engaging the platformcentrally and a flat metal spring extendingto the edges of the platform.

4. ln a bed spring re-enforcement, the

combination of. a supporting bar; a flexible platform formed with aperiphery of flat metal bars and cross bars; and a spring connectionbetween the platform and the supporting bar engaging the cross bars 5,ln a bed spring rie-enforcement, the

combination of a supporting bar; a flexible platform formed withr aperiphery of flat metal bars andl crossbars; and a spring connectionbetween the platform and the sup-` porting bar engaging the cross barsand the peripheral bars.

In testimony vwhereofl have hereunto set ii 1y hand.
